Answer:
AC BA BC shortest to longest.
Explanation:
All triangles have 180o in their interior angles. So A + B + C = 180
5x - 4 + 2x + 3 + 3x - 9 = 180 Combine the like terms on the left.
10x - 10 = 180 Add 10 to both sides
10x - 10 + 10 = 180 + 10
10x = 190
x = 190/10
x = 19
So <A = 5x - 4 = 91
<B = 2x + 3 = 41
<C = 3x - 9 = 48
Total 180
So the largest Line is opposite 91 and it is BC
The Middle sides line is opposite 48 and it is BA
The smallest line is opposite 41 and it is AC
AC BA BC shortest to longest.
